Really annoying sound :biggrin:, but still very cool!

Demonstration of the third version of Rhythmicom built by Leon Theremin at Moscow State Conservatory in early 1960-s. The first Rhythmicon was developed by Leon Theremin for Henry Cowell in 1932. It was the first rhythm machine ever built.



EDIT: A more hightech rhythm machine: EKO COMPUTERHYTHM

I worked (installed modern data processing systems not related to fire-control) on all the BB-62 class ships in the 80's when they were pulled out of mothballs again for active service. Most of the old 'analog' computers were still operational (with upgrades to automatically input signals from modern computers) to find firing solutions for the big 16 inch guns. Synchro data transmission links were used to slave data to the analog machines. http://www.eugeneleeslover.com/ENGINEERING/OP2074.html

I hope they're in a museum somewhere !

An old friend served on the Missouri in WW2 working on those mechanical computers.

As recently as 70's we had mechanical analog boiler controls that used compressed air , bellows, cams and levers .
Pneumatics works fine, is impervious to EMI, just needs clean dry air. The steady 'hiss' when all is going well is comforting.

What did we learn here? Always keep topologists busy, for otherwise they might produce youtube videos!

I'm guessing I'm overqualified to be an FBI agent. :biggrin:

Denver Post; "An off-duty FBI agent allegedly accidentally shot a man in the leg early Saturday after the agent’s gun fell from his holster..."

His holster looks suspiciously like the crack of his butt. o0)

ps. Do they not teach FBI agents about the "safety switch" on a gun? Seriously. It's been 40 years since I last took a class on handguns, and even I remember that. :rolleyes:

some Glocks don't have one. They assume the user means it when he pulls the trigger.

Play the video back at 1/4 speed and clearly it goes off when he grabs it, and his finger looks to be on the trigger..

I prefer 1911's myself.

Don't need to. Can't imagine a gun going off otherwise.

That was the gun I was trained on.

Nice production.

btw, did you see the video from Hawaii the other day?

Guns.
Some people should not be allowed to own them...



From the context of the video, the shooter did not know who his neighbors were.

Look up Idiots with guns on youtube. Hilarious, but one has to be prepared to hear a couple of ugly words. I like the one who actually looked down the barrel of his rifle. Beside the obvious stupidity, how did he expect to view something without light?

It wasn't that bad, they all seemed to have had a blast.

Was that the video ?

Sure looks like an over-reaction. With all those witnesses the big guy could easily wind up in the 'NICS Denied' database.

ps. Sorry. I'm pretty much "gun" illiterate. They are the least of my interests.

The folks who have to approve any gun purchase from a dealer. It's done in a few minutes by phone call. Shoulda stopped the Parkland kid but that's another whole story and covered elsewhere.

Sorry for the undefined acronym..

Look at this guy's clothes. (I posted a link instead of embedding the video so that the timing works properly since it doesn't work with embedded videos)

If you are not on limited bandwidth, play it at the highest resolution you can and at full screen.

Time 2:23. Take a look at the guy's coat. That fibre weave at the top of the back is Gabardine :oldlove:. The one in the cuffs is a smaller weave, but also Gabardine. The cuffs look even better because the weave is smaller. I love Gabardine. It's just awesome.
